用于往复式制冷压缩机的轴承装置
摘要：
本发明的装置应用于一种压缩机，该压缩机包括轴承毂（30），该轴承毂容纳曲轴（40）并且至少具有第一和第二轴承部分（31,32），该第一和第二轴承部分被周向凹槽（33）间隔开。所述曲轴（40）具有由从所述轴承毂（30）的周向凹槽（33）偏置的周向凹槽（43）间隔开的至少第一和第二支撑部分（41,42）。所述轴承部分（31,32）和支撑部分（41,42）的至少一个的轴向延伸超过径向支承所述曲轴（40）所需的轴向延伸，所述第一和第二轴承部分（31,32）与所述第一和第二支撑部分（41,42）一起相应地限定第一和第二径向轴承区域（M1,M2），所述第一和第二径向轴承区域具有曲轴（40）的径向轴承所需的轴向延伸，提供由粘性摩擦引起的较低损失。
摘要（英）：

The arrangement of the present invention is applied to a compressor which comprises a bearing hub (30) housing a crankshaft (40) and presenting at least a first and a second bearing portion (31, 32), spaced apart by a circumferential recess (33). The crankshaft (40) presents at least a first and a second support portion (41, 42), spaced apart by a circumferential recess (43), which is offset from the circumferential recess (33) of the bearing hub (30). At least one of the bearing portions (31, 32) and support portions (41, 42) has an axial extension superior to that required for radially bearing the crankshaft (40), the first and second bearing portions (31, 32) defining, with the first and second support portions (41, 42), respectively, a first and a second radial bearing regions (M1, M2) having the axial extensions required for a radial bearing for the crankshaft (40), presenting lower loss by viscous friction.
